6 | * struct s3c24xx_mci_pdata - sd/mmc controller platform data | |
7 | * @no_wprotect: Set this to indicate there is no write-protect switch. | |
8 | * @no_detect: Set this if there is no detect switch. | |
9 | * @wprotect_invert: Invert the default sense of the write protect switch. | |
10 | * @detect_invert: Invert the default sense of the write protect switch. | |
11 | * @use_dma: Set to allow the use of DMA. | |
12 | * @gpio_detect: GPIO number for the card detect line. | |
13 | * @gpio_wprotect: GPIO number for the write protect line. | |
14 | * @ocr_avail: The mask of the available power states, non-zero to use. | |
15 | * @set_power: Callback to control the power mode. | |
16 | * | |
17 | * The @gpio_detect is used for card detection when @no_wprotect is unset, | |
18 | * and the default sense is that 0 returned from gpio_get_value() means | |
19 | * that a card is inserted. If @detect_invert is set, then the value from | |
20 | * gpio_get_value() is inverted, which makes 1 mean card inserted. | |
21 | * | |
22 | * The driver will use @gpio_wprotect to signal whether the card is write | |
23 | * protected if @no_wprotect is not set. A 0 returned from gpio_get_value() | |
24 | * means the card is read/write, and 1 means read-only. The @wprotect_invert | |
25 | * will invert the value returned from gpio_get_value(). | |
26 | * | |
27 | * Card power is set by @ocr_availa, using MCC_VDD_ constants if it is set | |
28 | * to a non-zero value, otherwise the default of 3.2-3.4V is used. | |
